Description
Technical field
The utility model provides a kind of interconnection technique that makes CCFL (Cold Cathode Fluorescent Lamps or title Cold Cathode Fluorescent Tube) present better connection effect in backlight module (Back Light Module), especially is fit to be applied to the enforcement of LCD (Liquid CrystalDisplay) or other relevant backlight module.
Background technology
In recent years, it is the traditional monitor of core technology that LCD has replaced with cathode-ray tube (Cathode Ray Tube) gradually, and going out to present abundant light source and color in limited space with the technology of backlight module, it characteristic such as has gently, approaches and is better than traditional monitor.
Also further comprised in the aforementioned backlight module in order to produce the CCFL of light source, as shown in Figure 1, the interconnection technique of this CCFL, comprised a control circuit board 10, CCFL 20 that at least one is connected with control circuit board, each CCFL 20 has more than one electrode pin 21.The means of prior art in order to make control circuit board 10 be connected with CCFL 20, be on control circuit board 10, to have set in advance more than one plug socket 11, this plug socket 11 is to be electrically connected in the circuit of being laid on the control circuit board 10 12, and be provided with a connection-peg 22 in each CCFL 20 end, this connection-peg 22 is integrated the extended electrode pin 21 of institute, after treating that the assembler plugs pairing plug socket 11 with each connection-peg 22, can make CCFL 20 be electrically connected on the control circuit board 10.
But this kind makes CCFL 20 be electrically connected in the structure of control circuit board 10, be see through aforementioned plug socket 11 to reach with cooperating of connection-peg 22, so prior art or can produce following problem points on the implementation with the prior art similar technique:
Plug socket and connection-peg need be set, and then cause the increase of production cost, and except the increase of material cost, also can cause on the industry and must bear the cost of getting the raw materials ready, purchasing and check.
Plug socket and connection-peg can make originally that smooth-going control circuit board surface presents tangible protruding aspect after combination, and order is provided with the space and is restricted.
Because plug socket and connection-peg are raised in the control circuit board surface, therefore when radiator fan relevant in the LCD carries out forced air supply, plug socket and connection-peg can cause the obstruction of circulation of air, and are covering dust easily, even cause the delay of bacterium and waste gas.
The set metal structure that is used for being electrically connected on plug socket and the connection-peg, can be because exposed and long electric current passes through, and the surface that makes metal structure produces oxide-film, and oxide-film can make resistance value therebetween increase, and influence life-span of CCFL, and can cause hear rate, not only can waste energy and also have hot problem.
If plug socket and connection-peg be during loose contact, also can cause the problem that CCFL can't start.
The utility model content
The purpose of this utility model is, has at the prior art problems point, and it is simple to design a kind of structure, and durability is good and space utilization degree is higher, do not influence the syndeton of radiating airflow again.
The utility model is a kind of " the cold-cathode lamp pipe connecting structure of backlight module ", this backlight module comprises a control circuit board, CCFL that at least one is connected with control circuit board at least, each CCFL has more than one electrode pin, wherein: the bonding pad of the direct solid welding of electrode pin of an above cooling negative electrode fluorescent tube of the lateral margin horizontally set of control circuit board, this bonding pad have the guiding access that at least one power supply utmost point pin connects.Aforementioned connecting portion is to can be the breach that is depressed in the control circuit board lateral margin, or is the dissected valley that is depressed in the control circuit board lateral margin, and guiding access can be the end of the circuit of laying on the control circuit board.
Compare in prior art, the utility model technological means has following advantage at least:
Plug socket and connection-peg need be set, effectively reduce production cost, except saving material, and low industry be born the cost of getting the raw materials ready, purchasing and check.
CCFL can not cause the aspect of control circuit board rat with after control circuit board is connected, and it is more unrestricted that it is provided with the space.
Do not have and covering dust or causing bacterium and the problem of waste gas delay.
Effectively reduce the surface and produce oxide-film, and solved, and influence cold-cathode lamp tube lifetime, hear rate because of resistance value increases ... etc. problem.
Do not have between plug socket and connection-peg and contact bad problem.

The specific embodiment
Following foundation technological means of the present utility model lists the mode that is suitable for the utility model enforcement, and cooperates graphic explanation as back:
Shown in Figure 2, be the three-dimensional exploded view of the utility model embodiment, disclose wherein a kind of embodiment of " the cold-cathode lamp pipe connecting structure of backlight module " among the figure.It is in the lateral margin of the control circuit board 10 of backlight module, the more than one bonding pad 13 of horizontally set, this bonding pad 13 has the guiding access 14 that at least one power supply utmost point pin connects, this guiding access 14 can be the end of the circuit of laying 12 on the control circuit board 10, or for being embedded in the sheet metal of circuit 12 ends; Wherein, bonding pad 13 is except can smoothly being located at the lateral margin of control circuit board 10, and can be the breach that is depressed in control circuit board 10 lateral margins or be depressed in the dissected valley or the slit of control circuit board 10 lateral margins, be as an illustration during this is graphic with the breach that is depressed in control circuit board 10 lateral margins.
As shown in Figure 3, it is the three-dimensional combination figure of the utility model embodiment, CCFL 20 has two electrode pins 21, these two electrode pins 21 are directly to be welded in the adjacent bonding pad 13 with solid welding thing 15 respectively, and present connection status firmly inseparable, that can not get loose, and can both remain on the good state that is electrically connected with pairing guiding access 14 with seasonal each electrode pin 21.
In view of the above, enforcement of the present utility model can effectively reduce production costs, save material, and make bear on the industry get the raw materials ready, buying and inspection cost reduced many.And because CCFL 20 is that side direction is connected in control circuit board 10, therefore, the surface of control circuit board 10 can not present the state of projection, and it is more unrestricted that it is provided with the space, and does not have and covering dust, influence heat radiation ... etc. problem.
Except that this because CCFL 20 is that side direction is connected in control circuit board 10, and the contact site of electrode pin 21 and guiding access 14 is coated by solid welding thing 15 also can, does not have the problem of surface generation oxide-film, does not more have the situation of loose contact.
